World Water Day, celebrated annually on March 22, is a global observance highlighting the importance of freshwater. According to the United Nations, in 2022, 2.2 billion people lacked access to safely managed water services, meaning that they had to queue for water or access it from unprotected dugs, lakes, rivers, or ponds.
In the Netherlands, everyone can access clean water straight from the tap. However, during peak demand periods, some of the Dutch provinces suffer water shortages. In 2020, for instance, there was not enough water to meet demand peaks in Gelderland and Overijssel, in the western part of South Holland, and in the province of Groningen. Therefore, the National Insitute for Health (RIVM) called for action to secure the drinking water supply.
After centuries of dealing with water, the Netherlands remains one of the world-renowned leaders in water tech. Here are three Dutch companies reshaping water technology.
1. Ferrate(VI) technology: disrupting water treatment
The Meppel-based Ferr-Tech, developed Ferrate(VI) technology, a powerful oxidant that effectively removes contaminants from water. Unlike traditional treatments, Ferrate(VI) not only purifies water but also coagulates suspended particles, making it a versatile solution for various water treatment needs. This technology is particularly promising for industrial applications, where water quality is critical for operations and environmental compliance.
This Ferrate(VI) stands out for its ability to treat a wide range of pollutants, including organic compounds, heavy metals, and pathogens. Its application can significantly reduce the environmental impact of industrial wastewater, contributing to cleaner waterways and healthier ecosystems. As industries seek sustainable solutions, Ferrate(VI) offers a robust alternative to conventional treatment methods, aligning with the goals of World Water Day by promoting clean water for all.

2. Hydraloop: Recycling Water for Sustainable Living
Hydraloop, instead, has developed an innovative water recycling system that aims to reduce domestic water consumption by up to 45%. The system collects and treats greywater—wastewater from showers, baths, and washing machines—and recycles it for reuse in toilets, washing machines, and garden irrigation. By integrating Hydraloop into residential and commercial buildings, users can significantly decrease their water footprint and contribute to sustainable water management.
The technology behind Hydraloop involves a six-step process that includes sedimentation, flotation, dissolved air flotation, foam fractionation, and disinfection. This comprehensive treatment ensures that the recycled water meets high-quality standards, making it safe for various non-potable uses. With growing concerns about water scarcity, Hydraloop offers a practical solution for households and businesses to conserve water without compromising on hygiene or convenience. Its commitment to impactful water conservation has been recognized with multiple prestigious awards, underlining its key role in reducing global water waste.

3. HULO: AI-driven solutions to cut water waste
HULO, hailing from Leeuwarden, is leveraging AI to combat water waste in urban environments. Their solutions monitor water usage in real-time, detecting leaks and inefficiencies in water distribution networks. HULO helps municipalities and water utilities optimize their water management practices by providing actionable insights, reducing wastage and enhancing operational efficiency.
HULO's approach not only saves water but also reduces the energy required for water treatment and distribution, contributing to overall sustainability. In addition to promptly spotting leaks, the company also guides water managers to monitor their pipes, helping them locate sensors. Despite not needing historical data on leaks, the system remains effective at spotting anomalies quickly.

Global efforts and the role of World Water Day
World Water Day reminds us of the global commitment to achieving Sustainable Development Goal 6: ensuring the availability and sustainable management of water and sanitation for all. In further committing to this goal, technology is instrumental to guaranteeing water access to everyone.
From advanced treatment technologies to AI-driven efficiency solutions, the future of water conservation lies in the hands of pioneering companies and supportive ecosystems. By embracing these innovations, we can ensure that water remains a precious and accessible resource for generations to come.
